DS, this looks very similar to what I did to my OEM mufflers, and to the OEM tips. I have since that time removed those OEM mufflers, and tips, and....
they are available for sale...if someone on this forum wanted to TRY out a set of OEM mufflers and tips that have already been drilled out, rather than drill your own. This would allow a rider to TRY out the drilled version, and if they didn't like it, then could reinstall their non-drilled mufflers.
I have since that time installed aftermarket mufflers and Torq Loops, and the drone is 100 % gone. I have always agreed with Deer Slayer as to where the drone is located, and what causes it, and what it actually is. I would say to any and all that have aftermarket mufflers.....the drone is NOT caused by your aftermarket mufflers, so don't be upset with the manufacturer or supplier, as it is not their fault. Honda simply built a good enough OEM muffler that it masks the drone. Once you remove those OEM mufflers, you will most likely....."most likely"...hear the drone, unless you strain your back from lifting too heavy of a wine goblet.
Quite Frankly, I think the best set up for these bikes is the OEM mufflers and tips. But, as we all know, to each his own.
I am happy with what I have now, and how the bike sounds, and performs, but given 20/20 hindshight, I would have stayed with OEM mufflers. My personal reasoning for making the change was more due to the "need" to feel the bike through the seat of the pants, because I cannot hear the bike with the OEM mufflers now. Due to my recent hearing loss, the bike sounds like it is an electric bike, when using OEM mufflers. That can be disconcerting when riding in twisties, as we get used to hearing our bikes, and knowing how it is performing, gear shifts, etc. By changing to aftermarket mufflers and Torq Loops, I can now "FEEL" the bike better.
